•"In this scenario, the
Appearance Agent does not have any way of
• knowing Bob's dialog state information,
except through Bob. This
•
could be because the Appearance Agent is not part of a B2BUA, or
• perhaps Bob is remotely registering. When Bob registers, the
• Appearance Agent receives a registration
event package notification
• from the registrar. The Appearance Agent then SUBSCRIBEs to
Bob's
• dialog event state. Whenever Bob's dialog state changes, a
NOTIFY is
• sent to the Appearance Agent who then
notifies the other other UAs in
•
the group.
•
• OPEN ISSUE: Does Bob PUBLISH to
select/seize an appearance, or
• does he just NOTIFY the Appearance
Agent?"
•
•Proposal: Use
NOTIFY instead of PUBLISH when
the Appearance Agent subscribes.
